[xwiki-users] component manager not initialized after install

Hello, I installed XWiki today and when I first tried to view the Wiki, I received the following error: Error 500: Component manager has not been initialized before lookup for [org.xwiki.model.reference.DocumentReferenceResolver] for hint [currentmixed] Could anyone give me advice about this error message? I installed it on Websphere AS 6.1, fix level 23, and Oracle 9g. I modified the Hibernate config file to use Oracle with "OracleDialect" pointing at my database. I also added the dummy data source. I added the PNG mime-type and restarted WAS. I added ojdbc41.jar to the WEB-INF/lib folder of the WAR. I did change the Web app context to "wiki" instead of "xwiki", but I didn't think that should make a difference. Thanks in advance, Scott McMasters
